From 1d3e71bd9710593cc0d7216b0ce9898b8e89aeef Mon Sep 17 00:00:00 2001 From: Nick Hainke Date: Thu, 4 May 2023 21:13:33 +0200 Subject: treewide: remove files for building 5.10 kernel All targets are bumped to 5.15. Remove the old 5.10 patches, configs and files using: find target/linux -iname '*-5.10' -exec rm -r {} \; Further, remove the 5.10 include.
